Sharp shows at the SID Display Week 2009 its LS013B4DN02 1.35-inch Monochrome Square Memory LCD display. Sharp’s new LCD is basically an ultra low-power graphic display that features built-in pixel memory, high reflectance and ultra-thin mechanicals. We can already see the Memory LCD being used on Sharp’s mirumo 934SH mobile phone.
The display has a refresh rate of just 1 Hz. It has a 10:1 contrast ratio and 50% of reflection ratio. The LS013B4DN02 needs only a single 5V supply.
It costs $25.
